Chris Christie released from hospital after COVID-19 diagnosis

Former New Jersey governor and ABC News contributor Chris Christie said he was released from the hospital on Saturday, one week after his COVID-19 diagnosis.

Christie announced he tested positive on Oct. 3. He said that day he was checking into New Jersey's Morristown Medical Center as a precautionary measure due to his history of asthma.

Christie tweeted Saturday morning, "I want to thank the extraordinary doctors & nurses who cared for me for the last week. Thanks to my family & friends for their prayers. I will have more to say about all of this next week."

Christie on Saturday did not discuss his symptoms, but when he announced his diagnosis, he said he was "feeling good" and had "mild symptoms."

Christie helped President Donald Trump prepare for the presidential debate at the White House on Sept. 28 -- three days before the president's Oct. 1 COVID-19 diagnosis.

Christie also attended the Sept. 26 White House Rose Garden event where Trump announced his nomination of Amy Coney Barrett to the Supreme Court. At least 14 people who attended the Rose Garden event have since tested positive.
